Egypt's presidential race may finally conclude this Sunday, according to the BBC. In the meantime, as former president Hosni Mubarak's health fluctuates in prison where he is serving time for his numerous crimes, both candidates Mohammed Mursi and Ahmed Shafiq have claimed the political seat.

The delayed results of Egypt's presidential run-off will be announced on Sunday, the election commission has said.

It has been considering appeals by the two candidates - Mohammed Mursi of the Muslim Brotherhood and the former Prime Minister Ahmed Shafiq.

They have both claimed victory and say they will appoint unity governments.

Muslim Brotherhood supporters have been demonstrating in central Cairo to demand the announcement of the result. The BBC's Jon Leyne in the capital, Cairo, says the country is deeply polarised, and there are fears that the final announcement might only make matters worse.

Results from last weekend's run-off election were originally due out on Thursday.
